Effects of Endocrine Disruptors Found in a Great Lakes Sewage Treatment Plant Effluent on the Reproductive Success of Adult Female Fish at Both the Individual and Population Level

Building on their work concerning the effects of endocrine  disrupting chemicals (EDCs) on fish, researchers will tackle three  questions. First, they will determine if female fathead minnows  suffer reproductive abnormalities when exposed to wastewater  effluent containing EDCs. Second, they will attempt to link female- specific reactions to particular estrogens or androgens in the  wastewater. Third, they will determine if EDCs might reduce the  viability of populations by disrupting gene flow. The effluent from  many Great Lakes sewage treatment plants and paper mills contains  EDCs. Such wastewater lowers the reproductive potential of male fish  in the laboratory. This project will be one of the first to address  how EDCs in effluent might affect fish at the population level.
